What board are you referring to?

The MAX II CPLD is too small to implement the JTAG-to-Avalon-MM bridge (I've tried), so it will most likely be using an SLD_VIRTUAL_JTAG component, which means its access method is totally custom. You'd need to use either a power monitoring GUI supplied by the board vendor, or read whatever code was used to implement the MAX II CPLD.

Cheers,
